Winstar LCD Display Module, Yellow / Green, STN, Positive, Transflective - Green Yellow 20x2

The Winstar LCD Display Module is a high-quality character display solution, engineered for clarity and reliable integration into a wide range of electronic projects and commercial devices. This module utilises an STN (Super Twisted Nematic) transflective screen with a positive display type, ensuring excellent readability in various lighting conditions, from bright ambient light to controlled indoor environments.

Featuring a built-in ST7066U controller IC, the module offers a default 6800-series 4/8-bit parallel interface, providing a stable and widely compatible connection for embedded systems. Its construction is designed for durability and consistent performance across an extended operating temperature range, making it suitable for demanding applications.

Key Specifications

The display presents a 16-character by 4-line format, with each character formed by a 5x8 dot matrix that includes a cursor function. The transflective mode offers a balanced view, leveraging both reflected ambient light and its own backlight for optimal visibility. A vibrant yellow/green LED backlight ensures the display is clear and easy to read, even in low-light conditions.

Design and Compatibility

Engineered with versatility in mind, the module supports a logic voltage range from 3V to 5V, with a negative voltage generator optional for +3V power supply systems, enhancing its flexibility for different circuit designs. The 1/16 duty cycle contributes to stable operation and clear character definition.

Its compact form factor allows for integration into space-constrained designs without sacrificing screen area. The module is a robust and dependable choice for developers and engineers seeking a proven display component for prototypes, industrial controls, instrumentation, and consumer electronics where clear alphanumeric output is essential.
